Oh My Ghost and Heart to Heart do not have similar plots, but they are both enjoyable to watch. The writing and directing along with the acting and chemistry worked well together to produce two wonderfully entertaining dramas. Although the plots are different, the female leads display a lovable awkwardness that subtly influences the charmingly over-confident male leads. Both dramas are definitely on my rewatch list.

The Man in the Mask is a bit more lighthearted and comedic, and less advanced than Healer (no freakily cool technologies or hacker Ahjummas) but I got the same feel with both - a main lead who has an "everyday" role where he is somewhat cowardly but transforms into an alter ego who is heroic. Both have to conceal their heroic identities from the girl that they love.

you might like to watch it for the main actor Jo Jung Suk singing in the other drama. (Another kind of personality)

both are based on novels from the same author Gu Man. One is more focused on the career and the other is more focused on their love and past.

They are both about ancient people time traveling to modern times. They have the same quirky feeling of how to adopt to modern technology and how to solve their own mysteries.

...both are dramas about nice guys falling for celebrity girls. Heartwarming, sweet and original romance dramas.

Both are low-key dramas featuring a main character who works as a pickpocket. Ruler of Your Own World is somewhat more melodramatic while Yoona's Street has a slice-of-life vibe to it.

Both dramas deals with characters pretending to be someone they are not and the hi-jinx and complication that comes after to keep the lie going. Both are lighthearted rom-com that are enjoyable to watch with handsome male leads.

Ho Goos Love can be in some aspects related to Stand up. Both are great dramas that start as a comedies but end up being something much more than you have ever expected. From both you will learn that power of love and friendship can heal you from deep emotional scars. Stand Up is however about highschoolers while Ho Goos Love is about people in their 20s.

You won't relate them one to another, but in the end you'll realise they are so similar.

Supernatural abilities, psychopaths, mysteries from the past :P Evem similar OST :D

Both of the girls have amazing, supernatural abilities and they solve criminal (and not only) mysteries.

Quite different dramas, but there are some similarities, like both couple knew each other when they where children. There was a crime, they lost parents and now we have a big mystery.

And there is great chemistry between couples, a little of comedy and action ;P
